TVOC Fixed VOC Detector

For Continuous VOC Monitoring

​

TVOC is a fixed continuous PID detector for the detection and measurement of total volatile organic compounds (TVOC). Its photoionization detection (PID) sensor capabilities utilise advanced patented Fence Electrode technology with increased resistance to humidity and contamination.

​

A robust fixed PID detector, TVOC has a selectable detection range of 0 – 10 ppm, 0 – 100 ppm or 0 – 1000 ppm and is ideal for use in manufacturing and process industries where VOCs are typically present.

​

With a 4-20 mA analogue output, TVOC can be simply integrated into a DCS control system to provide warnings and enable control of high VOC levels in the working environment.

​

The instrument’s ATEX approvals enable a 3 wire TVOC system to be used in Zone 2 hazardous areas without safety barriers, whilst its ATEX and IECEx approvals allow TVOC to be used in Zone 1 hazardous areas with safety barriers.

​

The TVOC fixed PID detector utilizes a diffusive sample technique resulting in fewer contamination issues compared to pumped systems, reducing lamp cleaning and servicing requirements.

​

Simple to install service and calibrate, TVOC requires no hot work permit and the PID sensor is accessible and changeable in a matter of seconds.

​

The TVOC is also available for use with a pumped system for applications where sample conditioning is required.
